Support multisampled depth texture bindings

Adds support for processing texture_depth_multisampled_2d bindings
reflected from Tint, and also removes Dawn restrictions against
multisampled depth. These restrictions were originally added in
https://dawn-review.googlesource.com/c/dawn/+/30240 to validate
against using a multisampled depth texture with a
comparison sampler. This is now disallowed by the language with
distinct binding types and builtins in WGSL. Previously with
SPIR-V, we inferred Depth if the texture was used
with a comparison sampler.

Also check Vulkan limits for supported sample counts.
